GEORGE MARTIN BRILL, OF PHILADELPHIA, PENNSYLVANIA;

CAR-AXLE BOX.

SPECIFICATION forming part of Letters Patent No. 324,220, dated August 11, 1885.

Application filed March 31, 1885. g (No model.)

To aZZ whom, it may concern:

Be it known that I, GEORGE MARTINBRILL, a citizen of the United States, residing at Philadelphia, in-the county of Philadelphia and State of Pennsylvania, have invented certain new and useful Improvements in Oar-Axle Boxes, of which the following is a specification, reference being had therein to the accompanying drawings, wherein Figure l is a side elevation of a part of a car, axle, wheel, and axle-box, showing my improvements. Fig. 2 is a broken longitudinal section of the rear portion of the axlebox, drawn to an enlarged scale, showing the dustshield and the collar on the axle. Fig. 3 is a like view, partly in elevation, of same. Fig. 4 is a horizontal section on line 1 1, Fig. 2. Fig. 5 is a broken perspective of the rear end of axle-box. Fig. 6isa perspective of removable cap or cover for back end of axle-box, and Figs. 7 and 8 are detail perspectives of parts of the dust-shield.

Myinvention has relation, generally, to caraxle boxes, and particularly to dust-shields for the rear end of same; and it has forits object to so construct the rear end of the axlebox and the component parts of the dust-shield that a simple, durable, and effective shield is provided for excluding dust and preventing escape of oil from the axlebox.

My invention accordingly consists of the combination, construction, and arrangement" of parts, as hereinafter described and claimed, having reference particularly to an axle-box having a single rear wall provided witharearwardly-projecting edge flange all around the same, forming an open or outside rear end chamber, which has a removable cap or cover and receives a plate of hard wood or other suitable material secured in a metal holder or plate having a hub loosely mounted upon the axle, projecting outside of said cap and entering an annular recess in the end of a collar or sleeve firmly secured to the axle between the wheel and axle-box.

In the drawings, A represents an axle-box, which, except as hereinafter described, may be of any ofthe usual or well-known construe tions, or as shown or otherwise, as desired. Box A has but aosingle integral rear wall, a, which has the usual axle-opening, a. All

around the outside edge of wall a rearward] y projects a flange, a which incloses or forms an open end or outside chamber, B, on or at the rear end of box A. r

0 represents a cap'or cover for chamber B. This cap is preferably made with an all-around edge flange, 0, to overlap the edges of chamber B and make a closed joint therewith, and has an axial opening, 0. Cap 0 is also provided with side flanges or lips, c, which abut against similar flanges or lips, 1), formed on the outside lateral surfaces of chamber B, as shown more plainly in Fig. 4.. These abutting flanges c and b are provided with registering openings 0 b, respectively, for passage of fastening-bolts b or other like devices,

whereby the cap 0 is susceptible of being re- I moved from box A. If desired, however, said cap may be otherwise suitably secured to box A.

In chamber B is placed an oblong, square, or other appropriately-configured block of hard wood or other suitable material, D, having axle-opening d. The block D is held by friction or otherwise in a metal holder or plate between its top and bottom flanges, e, and said plate has a hub, 6 loosely mounted on the car-axle 00, which hub projects beyond the removable cap 0, and its end 6 enters an annular recess, f, in asleeve or collar, F, firmly fastened to axle w by a set-screw, f, or other fastening device, between the car-wheel yand box A.

It will be noted from the foregoing that the opening (I in block D is circular, as shown, or that it and the hubopening of plateE snugly fit the axle; that the collar F covers the end of hub 6 to prevent access of dirt between the latter and the axle; that theinside surface, 0

of cap 0 impinges against the back of plate E,

and that the outer surface, d of block Dbears against the back of box-wall a,- consequently the opening a in the latter is effectually sealed against the access of dirt thereto and the escape of oil therefrom. As the block D and plate E do not revolve, their impinging or sealed surfaces do not wear, and therefore require little or no adjustment, and when once set up or affixed in their proper position on the box A need no furtherlooking after or attention.

\Vhat I claim is 1. An axlebox having rear open chamber, B, and cap 0, in combination with ZlblOCk, 1), plate E, and collar F, substantially as shown and described.

2. A dustshield for a car-axle box composed of a block, D, and holder E, havinghub 0*, substantially as shown and described.

3. The axle box A, having rear end flanged chamber, B, having outsidelugs, b, in combination with cap C, block D, plate or holder E, and collar F, substantially as shown and described.

4. The axle'box A, having chamber B and cap 0, in combination with block D and plate 1*],having lips e and hub a" projecting through gap {3, substantially as and for the purpose set ort l.

A. dustshield for car-axleboxes,oomposed of a non-rotating block and holder mounted on the car-axle and inclosed in a rear end chamber of the box, and having a hub projecting beyond said chamber, substantially as shown and described.

6. The combination, with box A, having end chamber, 15, and cap 0, having axial opening 0, of block D, holder E, having hub a", and collar F, substantially as and for thepurpose set forth.

In testimony whereof I am): my signature in presence of two witnesses.

GEORGE MARTIN BRILL.
